DECORATING APPARATUS.

Application filed March 25, 1926. semi No. 97,255.

My invention relates to decorating apparatus, and the apparatus isparticularly adapted for forming patterns in the coating on glasswarepreparatory to etching the same. The purpose of my invention is tosimplify the necessary apparatus, and render it more eihcient. Detailsof the invention will appear as the description proceeds.

In the accompanying drawings, forming a part of this specification,Figure 1 is a partial plan view, with parts brokenfaway, showingapparatus embodying'my invention; Figs. 2, 3 and 4 are sections on thelines 22, 3-3 and 44, respectively, .on Fig. 1; Fig. 5 is asideelevation of a detail; and Fig. 6 is a plan of the air control valve.

I have shown the apparatus mounted on a table 10, and, by way ofillustration, a

7 glass tumbler 11 is shown in position on chuck plate 12. The chuckplate is supported on the upper end of spindle 13 having a hollow 14therethrough bywhich air may be exhausted from the interior of thetumbler.

The spindle is mounted in a sleeve 15 which has fixed thereon an uppercollar 16 adapted to rest upon the upper side of table10 While a collar17 at the lower end of the sleeve prevents the spindle from rising withrespect to the table. A vacuum pipe 18 enters the lower end of thecentral bore 14 of spindle 13, and a stuffing box 19 prevents leakagearound vacuum pipe 18. Pipe 18 is connected by means of a flexible hose2O with exhaustingiapparatus, as will be explained later. V 7

An operating shaft 21 is mounted vertically in the table, and is drivencontinuously in a manner which will be describedlater; A

crank pin 22 is attached to shaft 21, and

drives intermittently a star wheel 23 fixed on the lower end of averticalshaft 24. Gear 25'is fixed on the upper end of shaft 24 above Itable 10 and meshes with a pinion 26 whichin turn drives gear 27 havinga comparative lyxsmall gear 28 attached to its upper side. The small;gear 28 is in mesh with a rela tively large gear. 29 on spindle 13.Inthis manner spindle 13 is driven from shaft 24. In order that therelative speed of the spindle may be varied and the length of successiveintermittent'steps may be adjusted, gears 27 and '28'are mounted in aslideway upon an adjustable member 30 and pinion 26 is mounted upon abracket 31 which may be adjusted about shaft 24,so that gears 27 andslide 51 and the partscarried 28 may be removed and other gears of esired dimensions used inplacethereof.

Above the table is abracket 32 having a V supporting sleeve 33 fixedupon bearing sleeve-34 which surrounds shaft 21. Bracket shaft 45 mesheswith gear 39 on shaft 37. A cam 47 is provided on the upper end of shaft45. Horizontal. slide 43 isprovided with a cam roller48 which isnormallyheld against cam 47 by meansof a spring 49; i

The other end of slide-43 is provided with a vertical slideway50 whereinthere moves a vertical slide 51. Slide 51' has a cam roller 52 adaptedto rest; upon acam 53 upon the end of shaft 37. Normally,

sufficient to keep roller 52 in contact With cam 53, but a spring 54 mayIce-added if .desired in order to assist gravity in maintain, ing thiscontact. i 7

Cylinder 57 is provided with apiston rod There is a needle or stylus rod59, supported by guidingportions 60, substantially parallel with piston rod .58. A member 61-connects rods. 58 and 59 so that they move together. On the'end of rod59 there is a head 62 which carries one or more needlesor sty- A vacuumpipe 64'lead's'into r the end of cylinder 57and actuates the cyle 100;

Immediately thereafter,pipe T0 is connected'to the various cylinders through pipe 80 and themanifold, and thereby the various needles are driven forward-intoengagement with the tumbler.

The various devices are set at the desired angles so as to contact'thetumbler at de{ at proper angles to the sired elevations and VVher-e theglass is prosurface of the glass. vided with a bulge 106, as shown-indrawlngs, and lines are to be placed upon the tumbler at thetopandbottomof this it is desirable to mount the fixed bulge, needle pointsas shown in Fig. 5, so that will the surface of the glass where theycome in styluspoints 63 are adapted to contact the glass midway betweenfixed points 7 3 and t is portion of' 73, and apply a pattern tothetumbler. The cams may be shaped to related, as will be readily seen,that .camfi'l.

"beneath tumbler 11' thebe substantially perpendicular to gears are so ifewer decorating members are used, the adv V I shown as a' tumbler, isplaced upon the chuck 12 while the valve not connected to the'clnick orto the v contact with it. In the construction shown,

so decorating members 'on be in and 53 make a complete revolution ateach revolution of shaft 21, and the tumbler is moved one step forwardduring each such revolution, so that stylus points 63 are moved througha pattern determined by the shapes of cams 47 and 53 during eachsuccessive rest period of the tumbler. By choosing proper dimensions forgears 27 and 28 the tumbler may be given a desired number of restperiods during one revolution thereof; It will be readily seen that thetumbler will precisely the same position at the conclusion of the finalrest in at the start of the first rest' period, and therefore, ifrotation of the tumbler is continued a little more than one completerevolution,

' in precisely the tracks they made during the first revolution. Thedimension of gear 98 is so chosen that there will be a little overone-complete revolution of gear '29, and consequently of the tumbler,while cam 97 is out of contact with roller 96. After this completerevolution of the tumbler, cam 97 actuates rack bar 93' and through itthe vacuum control valve; When the valve turns from operative positlontowards the position in which it is shown in Fig. 6, the vacuum isbroken first in pipe 80 and the connections to the various styluspoints, so that these points are withdrawn slightly before the vacuum isbroken within the tumbler.

The operative may removethe tumbler after the vacuum has been brokenwithin it, and replace it with another tumbler to be decorated, and theprocess will be repeated.

One operative may feed several of these devices. In the constructionshown, the controlling cams 97 are so located that they will operatealternately and the operative may feed the two devices in succession. As

will be seen from the length of cams 97, it will be readily possible toso locate them that the operative may take care of mor-e than two of thedecorating devices. This feature will be arranged as desired in view ofthe character of the design and the rapidity of the operation, etc.- 7
